I agree that this is both more effective and has the benefit of encouraging people to understand others in a deeper level. Taking the time to understand someone else handles stress differently (and has different strengths and weaknesses, preferences, ways of communication, etc.) is a level above just treating people the way oneself wants to be treated.

Anecdotally- I've had many experiences with my mother who adamantly insists she treats others the way she wants to be treated when, in fact, she has a very unique life experience that has generated some specific ideas of how she thinks people should behave, and in treating others the way she wants to be treated she tends to unintentionally generate miscommunication and awkward situations at best, if not sometimes conflicts and harm.

Would you not want to be listen to? Cared for? Considered? Is this not then the healthy expression of loving one as yourself.

Also, there are many who may harbor destructive habits and may need to be treated not for what they want in the moment but rather what best heals them and returns them to the best version of themselves. Understandably difficult to discern in most situations but difficulty is not a disqualification for pursuit of loving others as ourselves.
